Autoimmune hepatitis is a serious and a long lasting medical condition which causes the immune system of the body to operate against itself and attack normal cells and components present in the liver. This condition leads to an inflammation in the tissues of the liver and sometimes also results in liver damage.
The immune system as its original function is meant to protect from various infections by identifying the germs and bacteria, and destroying them as a self defense of the body.
Autoimmune hepatitis is a very serious form of illness that could slowly worsen when left untreated for an extended period of time. It could also lead to severe conditions such as cirrhosis or liver function failure. Cirrhosis is a condition which is also known as scarring of the liver. In this condition, the scarred liver tissues replace the healthier tissues in the liver and restrict the blood flow through the liver. When this occurs the liver stops functioning properly.
Types of autoimmune hepatitis
Type 1 autoimmune hepatitis
This is the most common type of the disease. Most people with this disorder have other autoimmune diseases like celiac disease, rheumatoid arthritis, or ulcerative colitis.
Type 2 autoimmune hepatitis
This is more commonly seen among children and young adults. This type is also associated with other types of autoimmune diseases.
An autoimmune disease is a serious disorder wherein the immune system of the body attacks its own cells and organs through proteins which are known as autoantibodies. This process where the body causes the attack is known as autoimmunity.
In a normal body the function of the immune system of the body is to make several proteins, also known as antibodies, which help in fighting the infections and defending the body from their ill effects.
However, in some people the body ends up making more autoantibodies. How this happens is still unknown. However, there are several environmental factors that could put someone at risk of developing autoimmunity. Environmental factors include all the factors that occur outside the body like the bacteria, viruses, other micro organisms, toxins and various forms of medicines.
As the name indicates, autoimmune hepatitis is caused by an autoimmune condition in which the immune system attacks the liver cells. This condition mainly occurs when the body’s immune system by mistake attacks its own organ and cells which causes inflammation and damage to the liver cells.
The actual cause for the autoimmune condition is not known. Genetic and environmental factors are implied in the development of autoimmune condition.
Treatment for autoimmune hepatitis depends upon the stage in which it is diagnosed. The treatment also depends upon the symptoms of the disease.
Some of the patients who are suffering from a very mild severity of this disease may not require any active form of treatment. For those who are recommended an active treatment with drugs, corticosteroids is the first preference of medications to start the treatment.
Corticosteroids are not of the same classification as the anabolic steroids that are specifically used to build muscle mass. Corticosteroids like prednisone are used as anti-inflammatory drugs which help in reduction of inflammation in any site on the body including the liver.
The doctor may even suggest other drugs instead of corticosteroids which have a similar anti-inflammatory action like azathioprine, mycophenilate mofetil or methotrexate. All these drugs are strong in nature and do carry their own share of side effects which should be discussed clearly with the doctor before starting on the treatment.
Around 90% of patients need treatment in some form or the other to maintain their body levels after the steroids perform the initial function of controlling the inflammation of the liver. Around 10% people may not require a follow up treatment and can live a normal life without any recurrence of inflammation in the liver for many years in their life.
Since the intensity of this disease depends upon each individual, there is always a risk of recurrence of the inflammation in the liver in the near future. The relapses are normally controlled by a round of steroids that may be prescribed to the patient for a temporary period.
Treatment strategies of Autoimmune hepatitis focus on controlling the autoimmune condition that lead to liver inflammation and damage.
Medications are used to slow down the activity of the immune system.
Prednisone and azathioprine are used to suppress the immune system activity. Prednisone have long term side effects like
After a period of treatment, it is kept at the lowest possible dose to control the symptoms.
Liver transplant is suggested if the response is less for conventional treatment, or if there is liver cirrhosis.
In transplant, liver from a healthy donor is used to replace the diseased liver. In some cases, only a part of the liver from the donor is used for transplant.
This part regenerates into new tissues after the transplant in both donor and receiver.
Is liver transplant an option for people suffering from autoimmune hepatitis?
A liver transplant is certainly a very effective treatment methodology adopted in case of patients where therapy through medications fails. It is also recommended for patients with decompensated cirrhosis that occurs due to autoimmune hepatitis. A liver transplant can help in treating patients with fulminant hepatic failure after being detected with autoimmune hepatitis.
In the long run, a liver transplantation is seen as good option as it increases the survival rate by 10 years.
The risk of a relapse of autoimmune hepatitis is not completely ruled out even after a liver transplant. It mainly occurs in case of patients who are suffering from compromised immune systems.
Sharing experiences about the treatment help in understanding and coping with the condition.
Being a part of a support group helps in understanding and sharing information about the disease and the treatment strategies.
Diet for patients suffering from autoimmune hepatitis
Patients suffering from acute symptoms of autoimmune hepatitis along with symptoms of nausea and vomiting are often suggested intravenous fluids to meet the body’s nutritional requirements. In most cases, the patients are able to consume regular food and diet. A diet with high caloric intake is often recommended for patients suffering from this disease.
Patients suffering from cirrhosis due to autoimmune hepatitis could develop ascites. Normally a diet that is low in salt is required for these individuals.
Patients are also recommended to keep up their intake of proteins due to the catabolic form of this disease and high chances of muscle wasting occurring due to this disease.
Most patients do not require hospitalization; however, it may be required when the condition flares up.
Long term bed rest is required to recuperate from the illness, though the patients begin to feel better soon with some physical activity.
Autoimmune hepatitis is definitely not a contagious disease. It is not even a disease that is inherited in the family line, even though there could be a tendency towards this disease in some families. Children and grandchildren could have an increased risk of acquiring autoimmune diseases associated with thyroid, liver conditions, or arthritis. It is not definitive that those who have this disease in their family will surely contract it, but the risk is always there.
